Abstract
Pyridylmethanimine-based ligands are used in aqueous media at neutral pH fo r the efficient living radical polymerization of hydrophilic monomers. High conversions (>90%), good molecular weight control, and low polydispersitie s (M-w/M-n < 1.20) were obtained for the polymerization of monomethoxy-capp ed oligo(ethylene glycol) methacrylate at 20 <degrees>C; faster rates, redu ced control, and higher polydispersities were obtained at elevated temperat ures.
